I got the order in record time and appreciate the good service. The Ott Light is the best light for my older eyes. So when the bulb burned out after many years, I was missing the bright light. Best light ever for senior citizens.

My mom had purchased the lamp that used these bulbs originally for her sewing she was doing. When I went away to college I needed a good light to read by and she let me have it. Ive used it for years, and the bulb burned out - so bought a replacement and sadly replacement had week spot in the glass at the end tip and well would not work when glass was broken.. Cant fault the company or amazon - just sometimes glass bulbs are difficult to judge if its thick enough or to thin.. I ordered a replacement already. Asked Amazon for refund / replacement.. - So while I wait another couple days id give 4.5 stars if I could - or more but had to be honest that im bummed not having the light working :/ ottlites are great - but waiting for bulbs is not fun.. more so when your a heavy reader like me.. will be waiting a few days for new bulb - then hopefully this one works and slots in nice/easy XD

Several years ago, I tried to find a replacement for my Ottlite Daylight gooseneck floor lamp, just to have a spare for when the bulb finally failed. I actually bought a couple of bulbs whose descriptions "promised" they would fit. But, they didn't -- not even close. Even the fabric store where I bought the light couldn't find compatible bulbs. I gave up the search. Luckily, the original bulb lasted more than 20 years (!). But, last week it finally failed, so my search began again. When I saw reviews for this bulb that referred to the OLDER Ottlite lamps, hope returned. This bulb FITS my Ottlite model U203030!!! It requires some careful muscle to push it in (it snaps sharply upon installation), but that's also true for the original bulb.If I could give this product 10 stars, I would.

I couldn’t find this style at store anywhere - I picked up a floor Ottlite at a yard sale but bulb burned out. I almost thought I got burned buying light - but luckily this older bulb model was available on Amazon. So for 25$ total I got a great Ottlite - still great value -
